Riding in sub-freezing temps can be tough! The proper clothing can help you go a long way. Wear multiple tight layers (as many as four or five on top, one or
two for the legs), use 3 mm or thicker neoprene booties over your shoes, very warm gloves (mittens or ski gloves can work wonders), and a skull cap or balaclava under your helmet. Avoid wearing jackets that aren’t breathable as you will sweat, stick with multiple
breathable layers and you will stay dry for the entire ride. Riding on a mountain bike or cyclocross bike will reduce your speed and wind chill somewhat, especially if you ride on the dirt/snow.
It might take a while to get dressed, but you may be surprised to find that you ride comfortably for an hour or three in weather that others think is better
suited for watching TV. The hardest part about riding in the cold is the first 10 minutes out the door before your body temperature rises from the effort, so wear your warm cycling clothes around the house for 15-20 minutes before you leave. You can also wear
a packable windproof layer that you can put in a jersey pocket after you warm-up. You’ll leave the house very warm, and you’ll be warmed up and riding comfortably in no time.
